I dont understand your statement about .3's.
Does the gun shoot straight in the first place? Find out by bench testing it.
Assuming your stance, grip, and trigger pull are all fairly consistent, concentrate on front sight focus and point of aim should equal point of impact.
Remember that range is more important with AS pistols. Even if you're aiming true and hitting spot on at 20 feet, you might miss entirely at 40.
